SPECIFICATION forming part Of Letters Patent No. 651,210, dated June 5, 1900.

Application filed January 9, 1900. Serial No. 863. N model.)

in the art to which it a-ppertains to make and use the same.

This invention relates to improvements in windows; and the object thereof is to provide an improved construction whereby both of the sashes may be quickly and readily reversed, so that the outer faces of the glass carried thereby may be conveniently cleaned from the inside of the room, thus obviating the danger and inconvenience incident to cleaning the outer faces of the glass when the sashes are in their normal position.

The invention consists in the details of construction which are fully set forth in the following specification, particularly pointed out in the annexed claims, and clearly illustrated by the accompanying drawings, in which Figure 1 is a perspective View illustrating our improved window, the parts being shown in position for the reversal of the sashes. Fig. 2 is a vertical sectional view showing the parts in their normal position, the sashes being shown in dotted lines. Fig. 3 is a similar view with swiveled plate in position for the reversal of the sashes.

Referring now more particularly to the accompanying drawings, A designates the window-frame, and B B two vertical strips carried by the inner faces of the side pieces of the frame and between which the sashes C and D are positioned. Strips B B are recessed, as illustrated, said recesses extending from a point a short distance above the meeting ends of the sashes to a point in line with or slightly below said meeting ends of the sashes. Secured in these recesses are the castings E E, formed at their lower ends with the raised circular portions F F, constituting pivots about which plates G G turn. These swiveled plates are formed each with two parallel longitudinally-extending slots H and I, the slot H being longer than the slot 1, so as to extend beyond the outer end of the latter.

The fixed pivots F F are each formed with the two parallel horizontally-extending slots J and K, the upper slot J extending to a point slightly beyond the center of the side rail of the upper sash and tl1elower,slot.,K

to the same point with respect to the lower sash. When these swiveled plates are swung downwardly to horizontal position, the slots H and I, formed therein, register with and form continuations of the slots J and K of the pivots, andwhen said plates are swung upwardly to their normal positions the outer ends of slots J and K are closed by the walls. of the circular openings formed in the plates, as will be readily understood.

Each sash has the outer faces of its side rails grooved longitudinally, as at L, said grooves being dovetailed or formed with flanges to retain the headed ends of pins or studs M, the opposite ends of the pins of the upper sash projectinginto slots J of the fixed pivots F F, while the. opposite ends of the pins of the lower sash project into slots K of said pivots. The pins have their ends headed to prevent withdrawal from the slots of said pivots. I

The upper sash at its lower end rests upon supporting-strips N, secured to the side strips of the frame, while strips 0 and P, respectively, retain the upper and lower sashes in their normal positions. The upper walls-of the castings are beveled, as illustrated, as are also the upper ends of the swinging plates, and the latter carry the gravity-catches Q, having the handle portions Q. The engaging ends of these catches engage the notches or openings R, formed in the upper walls of the castings.

The operation of our invention is as follows: As illustrated in Fig. 2 the sashes are in their normal positions. In this position the lower sash may be raised and lowered, it slidin g on the studs or pins M, which are retained in slots J and K of the pivots. To reverse the sashes, the catches are disengaged from the castings and the plates swung downwardly to horizontal position, as illustrated in Figs. 1 and 3, the slots formed therein registering with the slots of pivots F F. The lower'sash is then raised until its lower edge clears the retaining-strip P, when it may be drawn outwardly, its pins M moving in slots I of the plates. The sash can then be raised until it can be readily reversed, turning 011 pins M as pivots. The upper sash is drawn outwardly, its pins M moving in slots H of the plates, and reversed in the same manner. Thus the outer faces of the glass carried by said sashes may be readily cleaned from the inside of the room. The sashes may be quickly restored to their normal posit-ion and the swiveled plates swung upwardly and locked by the gravity-catches, the operation being clear from the description and drawings.

Many slight changes might be made in the details of construction without departing from the spirit and scope of our invention, and we do not, therefore, limit ourselves to the details of construction shown and described.

l-Iaving thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination with a window-frame, fixed pivots carried thereby and slotted horizontall y, and plates adapted to swing on said pivots and slotted, of a sash, and pins resting in the slots of said pivots and adapted to move in the slots oh the plates and movably connecting said sash with said pivots and plates, substantially as described.

2. The combination with a window-frame, and downwardlyswinging plates carried thereby, of a sash, and means for connecting said sash to said plates whereby the sash is adapted to slide vertically when the plates are raised, and is adapted to be drawn outwardly from the window-frame and reversed when said plates are swung downwardly, substantially as described.

3. The combination with a Window-frame, and downwardly-swinging slotted plates carried thereby, of a vertically-sliding sash, and pins upon which said sash slides, adapted to move in the slotted plates, whereby the sash may be. drawn outwardly from the windowframe when the plates are swung downwardly, substantially as described.

4. The combination with the window-fra me, and slotted swiveled plates carried thereby,

of the sash having grooved side rails, and studs engaging in the slots of the plates and grooves of the rails,substantially as described.

5. The combination with a window-frame, plates carried thereby and adapted to swing to horizontal position and formed with slots, catches for holding said plates raised, of the sash having grooved side rails, and pins adapted to move in said slots and engaging in said grooves, substantially as described.

6. The combination with a window-frame carrying swinging slotted plates and pins adapted to move in said slots, of a sash having a sliding connection with said pins, substantially as described.

7. The combination with the window-framecarrying pivot, plates formed with horizontally-extending slots, and plates adapted to swing on said pivot-plates and formed with slots adapted to register with the slots of the pivot-plates when said swinging plates are swung to horizontal position, of a sash, and pins upon which said sash is adapted to slide, resting in the slots of said pivot-plates and adapted to move in the slots of said swinging plates when the latter are in horizontal position, substantially as described.

8. The combination with a window-frame, downwardly-swinging slotted plates carried thereby, and gravity-catches for holding said plates raised, of a sash, and pins adapted to move in said slots and connected with said sash, substantially as described.

9. The combination with a Window-frame, and slotted swiveled plates carried thereby, of a sash having grooved side rails formed with retaining-walls, and pins engaging in the grooves of the sash and slots of the plates and having their respective ends headed, sub stantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
